There seems to be already another answers and I might be
missing a point, but you might mean you want to assigne an
address with simple number in its lower 8byte?
Such as,
3ffe:501:100e:2000::1
or
3ffe:501:100e:2000::2
not like
3ffe:501:100e:2000:200:eff:fe74:41d2
?
In that case, yes, you need to do ifconfig to assign former
kind of address. They are relatively easy to memorize and
useful as server addr. But you don't necessarily need to
manually assign it. You can use existing
ifconfig_ifname=
and
ifconfig_ifname_aliasnum=
also for IPv6.
(But there is no example for IPv6. I'll add examles.)
E.g. if you want to assign
3ffe:501:100e:2000::1 and 3ffe:501:100e:2000::2
to ed0, I think following configuration works.
ifconfig_ed0_alias0="inet6 3ffe:501:100e:2000::1 prefixlen 64"
ifconfig_ed0_alias1="inet6 3ffe:501:100e:2000::2 prefixlen 64"
(By the way, this is local addr here, and please not use
exactly same prefix at another place. :-)
Cheers,
